How is rectal cancer inherited

In recent years, various cancers have been rampant. As early as a few years ago, when people heard about rectal cancer, they felt particularly unfamiliar. However, with the passage of time, the incidence of rectal cancer has become higher and higher, so people have a certain understanding of the disease. So how is rectal cancer inherited? Let's take a closer look below.

The occurrence of rectal cancer may be related to genetic factors. Experts say that in the families of rectal cancer patients, many have a family history of cancer and many digestive tract tumors. Due to the change of genes in normal cells, cancer patients inherit a susceptibility, and with some stimulating factors, tissue cells grow rapidly and develop into cancer.

Genetic factors: In addition to patients with colorectal cancer caused by familial polyposis or malignant transformation of ulcerative colitis, about 5% to 10% of other colorectal cancer patients have a clear family history of tumors, collectively known as hereditary nonpolyposis colorectal cancer (HNPCC), also known as Lynch syndrome. The specific manifestations are:

(1) Three or more family members have colorectal cancer, two or more of whom are from the same generation; (2) At least two generations have the disease; (3) At least one of them was diagnosed with colorectal cancer before the age of 50.

Although genetic factors are beyond the control of patients, in daily life, if you continue to improve your body's resistance through diet and exercise, you can still reduce the harm of rectal cancer to the body. I hope our introduction above is helpful to you.
